Dynamics of a superconducting linear slider. Journal of Vibration and Acoustics, 137(2).1048-9002https://hdl.handle.net/10016/39918In this paper, the dynamic behavior of a one degree-of-freedom (DOF) contactless linear slider based on superconducting magnetic levitation is experimentally analyzed. The device is intended for precision positioning of an optic mirror in cryogenic environments. Different prototypes of this device have been tested at cryogenic temperatures (77 K), and their mechanical behavior characterized in the sliding direction for forced and unforced oscillations. Experimental results reveal that the slider is self-stable at the initial equilibrium position and the dynamic behavior fits well an underdamped harmonic oscillator. Finally, the device showed great potential for horizontal vibration isolation, acting as a low-pass filter with a resonance at about 0.9 Hz.4eng© 2015 by ASMEAtribución 3.0 EspañaDampingCryogenic mechanismNonlinear dynamicsSuperconducting magnetic levitationVibration isolationresearch articleIngeniería Mecánicahttps://doi.org/10.1115/1.4028928open access021002-12021002-4Journal of Vibration and Acoustics137AR/0000016661
